Slight difference between my passport name and my CFA ticket name...am i barred from the dec exam?

hi guys,

 erm... so there's a slight problem with my identification on my passport. on my passport my name tingwu is written as 'ting wu' (with the space in it), while i use tingwu almost everywhere for all identification purposes, the passport name retains the name from my birth certificate. would this be a problem that i wouldn't be able to enter the examination center? if so, who/where can i get help from?

thanks in advance!
